FRIEDERICK SUTER, OF PAW'IUCKET, RI-IODE ISLAND.

REED FOR WARPING-MACEIINES.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Application filed March 15, 1917. Serial No. 155,083.

To all whom it may concern:

Be it known that I, FRIEDERICK SUTER, a citizen of the United States, and resident of the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Reeds for Warping-Machines, of which the following is a specification.

This invention relates to improvements in reeds designed more particularly to take the place of the usual comb for spreading the warps on Warping machines, and the object of this invention is to provide a reed constructed in substantially a fan shape through which the warp threads are led from a rope form to be Wound directly upon the warp beam, which beam subsequently supplies the warp threads to a loom.

A further object of this invention is to provide a frame in which this reed is adjustably mounted so that it may be moved either up or down .to adjust the spread of the warp to fill beams of different widths.

A further object of the invention is to provide simple and efiective means whereby both ends of the reed may be raised or lowered in unison by the operation of but a single element.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1- is a diagrammatic view showing the action of my reed as applied to a warping machine.

Fig. 2- is an edge view in outline showing the application of my reed to a warping machine.

Fig. 3- is a front elevation showing a portion of my warp spreading reed mounted in a frame which is shown in section.

Fig. l is a detail showing the worm and the worm gears through which both ends of the reed may be adjusted simultaneously.

Referring to the drawings, 10 designates the frame portion of a warping machine in which my fan-shaped reed 11 is adjustably mounted. The upper bar 12 of this reed has projections extending laterally into vertically disposed grooves 13 in the frame 10, and these projections are provided with openings threaded to receive the long screws 14.. The lower edge 15 of this reed is also provided with a cross bar 16 whose ends extend into these grooves 13.

The essential feature of my improved warper reed is that the warp dents are set in substantially a fan shape; that is the dents are set on diverging angles from the lower edge toward the top, whereby as this reed is lowered, the warp threads 23 passing between the dents are opened up or spread farther apart, and when the reed is raised the warp threads are drawn together.

I do not, however, wish to be restricted to this precise arrangement as the reed may be reversed edge for edge if desired so that its action will be reversed to that above described.

In order to provide the raising and lowering action of this reed, the upper ends of the elongated screws 14 are mounted in the frame 17 and are provided with worm gears 18, which worm gears are engaged by worms 19. These worms are mounted on. a longi tudinal shaft 20 which extends through both, said shaft being supported in bearings 21 at either end thereof and is provided with a handle 22, the rotation of which causes both of the screws 14 to rotate both screws simul taneously so the reed may be either raised or lowered as desired and the movement of both ends will be in absolute unison which is of importance.

The usual method of spreading the warp threads in a warping machine is by a comb whose ends are mounted in a coil spring and which is actuated by a laterally disposed screw to spread the teeth of the comb, but this spreading action is quite limited and if the teeth are extended beyond a certain limited degree the spring becomes broken and the comb destroyed.

By the application of my reed to the warping machine this comb is done away with, and there can be no possible danger of breakage in adjusting this reed which has a far greater range in its spreading action than can possibly be obtained by the old style comb. I

I have illustrated one means whereby my invention may be carried out, but I do not wish to limit myself to this specific construction as various changes in shape and form of the various features and arrangements of the parts may be necessary. I, therefore, desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined by by said frame and engaging the ends of the the appended claim. top bar Within said guide grooves, and I claim: means for simultaneously rotating said A reed for warping machines comprising screws. 7 5 a frame having its sides provided with ver- In testimony whereof I aflix my signature 15 tically disbposed guide grooves, a top bar and in presence of a Witness. a lower ar both having ends projecting into said guide grooves, dents supported by FRIEDERICK SUTER' said bars and diverging from the lower bar WVitness: 10 to the top bar, depending screws supported HOWARD E.
